SeaMonkey/Firefox
Open the folder jre1.6.0_14/plugin/i386/ns7/ and drag the libjavaplugin.oji to either /usr/lib/mozilla/plugins or /root/.mozilla/plugins and choose “Link (relative).” This will enable java for Seamonkey and Firefox. To check, open Seamonkey 1.1.x and then Help -> About Plugins to see java there. In Firefox, Click Tools -> Addons -> Plugins and see a java plugin there. Go to java.com and click Do I Have Java?

OpenOffice
start OpenOffice and click Tools -> Options -> Java -> Add and then navigate to open the jre1.6.0_14 folder and click Select. It will show you that it recognizes Sun Java and then ask you to restart.

1. Download Sun Java from java.com. I prefer to download it to /mnt/home to conserve my ram. If you want the latest revision you can just click the big download button, and then select the “Linux (self-extracting file)” not the one with RPM in the name. If you want an earlier version then click “Other Java Versions” and then “Archive Java Technology Products Download” under Older Versions. (One of my job sites, for instance, works best, or at all, only with 6 update 7.)

2. When the file is downloaded open a Rox window and go to the place where you downloaded Java. First, Right-Click the java file and then choose Permissions and Yes to make the file executable. Second, Right-Click -> Window -> Terminal Here.

3. In the terminal enter
Code:
./jre-6u14-linux-i586.bin

(or whatever the name of the java file is). Don't forget the "./" to begin (that is period – forward slash, to indicate that the file is found in the current directory). You will need to scroll down with Enter to accept the license agreement and then the install program will create a folder named "jre1.6.0_14” or something like that.

Blackdown Java 1.4.2_03 DotPup (20MB) by flavour (dotpups no longer supported in later Puppys)
Work the way as the dotpup above, except that it's much smaller (56MB decompressed). Don't be scared by the name of the dotpup, it's working :-) If you don't need sound, you can get this even smaller version: 11MB download by flavour and kirk. Read MoreHome Page
